outofstockalert

What does outofstockalert function do?

I have checked all the AIP and RPAS documents but could not find any details on this function.

It is being used in one of my rule:

call mace -d "${domain}" -run -expression "sr0_al1, sr0_al2, sr0_al3, sr0_al4, sr0_al5 <- outofstockalert(dmn_plnhzn, sr0_a12defhzn, sr0_a1dayoos, sr0_a1ls_hzn, sr0_a1strpct, sr0_a2dayoos, sr0_a2ls_hzn, sr0_a2strpct, sr0_a3defhzn, sr0_a3dodso, sr0_a3ls_dod, sr0_a3strpct, sr0_a4ls_yst, sr0_a4strpct, sr0_a5dayoos, sr0_a5defhzn, sr0_a5ls_hzn, sr0_daysls, sr0_iscind, sr0_hstoos, sr0_hstls_, IpActCmdI, sr0_dodsothr, sr0_a3hzn, sr0_cscoosthr, sr0_hcthr, sr0_a12hzn, sr0_ls5thr, sr0_bhor, sr0_hcthr2, sr0_r3thr, sr0_ls3thr, sr0_r1thr, sr0_ls1thr, sr0_r2thr, sr0_ls2thr, sr0_r4thr, sr0_ls4thr, sr0_a4ls_pctsls, sr0_v4thr, sr0_art__1msk, sr0_art__5msk, sr0_art__2msk, sr0_art__6msk, sr0_art__3msk, sr0_art__1dow, sr0_art__5dow, sr0_art__2dow, sr0_art__6dow, sr0_art__3dow)”
